Subject: [net 04/16] net/mlx5: Fix err prints and return when creating termination table
Date: Tue, 18 May 2021 23:05:11 -0700	[thread overview]
Message-ID: <20210519060523.17875-5-saeed@kernel.org> (raw)
In-Reply-To: <20210519060523.17875-1-saeed@kernel.org>

From: Roi Dayan <roid@nvidia.com>

Fix print to print correct error code and not using IS_ERR() which
will just result in always printing 1.
Also return real err instead of always -EOPNOTSUPP.

Fixes: 10caabdaad5a ("net/mlx5e: Use termination table for VLAN push actions")
